The Xray was invented by accident. Not really invented but discovered.

While experimenting with electrical currents through glass cathode-ray tubes, Röntgen discovered that a piece of barium platinocyanide glowed even though the tube was encased in thick black cardboard and was across the room [source: Britannica]. He theorized that some kind of radiation must be traveling in the space. Röntgen didn't fully understand his discovery so he dubbed it X-radiation for its unexplained nature
